Split returns a string array that contains the substrings in this instance that are delimited by elements of a specified Unicode character array.
Example
string _strInput = "aaa bbb ccc ddd";
string[] words = _strInput.Split ( new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries );
foreach(string s in words)
{
// value of s: aaa, bbb, ccc, ddd
}
